23. Comfort Alert with Active Protection – (For systems
that use Comfort Alert.) Turn this feature ON to enable
active protection. This allows the thermostat to identify fault
codes sent by the Comfort Alert module when compressor
damage is possible and react to those codes by turning the
compressor off. Fault codes from the Comfort Alert module
will flash on the thermostat. If a Comfort Alert module is not
connected, or to disable active protection, turn this feature
OFF. If a Comfort Alert module is connected and this feature
is turned OFF, the thermostat will still receive and flash the
fault codes from the Comfort Alert module, but the active
protection will not be enabled to protect the compressor.
24. Heat Temperature Limit Range – This feature adjusts the
highest setpoint temperature for heat. The default setting is
99°F. It can be changed to a setting between 62°F and 98°F.
The "temperature limit" icon will be displayed to the left
of your setpoint temperature when using this feature. The
"temperature limit" icon will flash if an attempt is made to
adjust the temperature beyond the range selected.
25. Cool Temperature Limit Range – This feature adjusts the
lowest setpoint temperature for cool. The default setting is
45°F. It can be changed to a setting between 46°F and 82°F.
The "temperature limit" icon will be displayed to the left
of your setpoint temperature when using this feature. The
"temperature limit" icon will flash if an attempt is made to
adjust the temperature beyond the range selected.

28, 29 Select Fast Second Stage, ON or OFF –
Not available if configured for SS1. Selecting FA ON forces
additional heat stages to come on quickly when
to raise the temperature a few degrees above the room.
Select this setting if you want the heat to increase quickly
09/2020 11-HD17D1-1C-EN
Part No. 37-7775005
to advance the menu. Three
or
keys to operate within
.
is used
American Standard Silver 302 and 303 Touchscreen Thermostat
when you manually raise the temperature.
Selecting FA OFF allows the thermostat to calculate
an optimal time to bring on additional stages of heat.
When the
is used to raise the setting above the room
temperature additional heat stages may come on very
quickly or very slowly (up to 30 minutes later) depending
on recent system performance. Select this setting if you do
not require the additional heat stages to come on quickly
when you manually raise the setting and want to allow the
thermostat to stage based on recent system performance.
The Fast Cool feature operates the cooling stages in
the same manner as Fast Heat, On or Off when the
temperature is lowered below the room setting.
30. Select Remote Temperature Sensor Enabled – ON
enables a remote sensor connected to thermostat and
displays the sensor temperature in the clock digits. OFF
(default) indicates no remote sensor connected or enabled.
31. Select Remote Sensor as Indoor or Outdoor – If 30
is enabled, select Indoor or Outdoor Remote. Default is
Remote Indoor.
32. Select Local Sensor Disable – If 31 is selected Indoor, the
thermostat Local Sensor can be disabled so the displayed
temperature will be from the Remote Sensor. Default is On
LS. To disable the Local Sensor, change selection to OFF
LS.
33. Select Dual Fuel Feature (dF) – This feature is applicable
only in heat pump modes (HP1, HP2). Enables (On) or
disables (Off) dual fuel feature of thermostat.
34. Select Dual Fuel Temperature – With dF selected On
and outdoor remote sensor available, select the outdoor
temperature the thermostat will use to determine when to
switch to gas heat and shut down the compressor. When the
outdoor temperature falls below the selected temperature
the gas heat will begin. Default is 35°, but can be set in the
range of -5 to 50°. A lower setting will delay the start of gas
heat allowing cooler temperature in the home.
35. Select Dual Fuel Setting – With DF selected On and no
outdoor sensor, select the dF setting from 01-09. Factory
default is 05. The dF setting influences when second stage
comes on. The factory default creates a separation of
approximately 1°F between stages. Increasing the setting
decreases the separation between stages. Decreasing the
value increases stage separation. This adjustment allows
a small change in the operation of your heat pump system
versus your auxiliary system relative to the thermostat
adjustment. The higher the number the sooner the auxiliary
stage energizes for better comfort. The lower the number
the longer period of time before auxiliary is energized for
more economy.
Note:
This setting is not minutes or degrees. It is numeric
setting that will influence the internal thermostat
calculation for staging.
36. Select Compressor Delay (Cd) – For use with Dual
Fuel System. After the auxiliary heat is turned on, the
compressor(s) shut down is delayed for the time selected
(in seconds). This delay is factory set to 60, but can be set
in the range of 0 to 99.
37. Select Auxiliary Off (AO) – Applicable with HP1 or HP2
selected with outdoor sensor. Select the temperature that
will inhibit the auxiliary heating stage. As long as the outdoor
temperature is above the selected temperature, the auxiliary
heat will not turn on. The default setting is 80°(disabled),
